摘要： A method and device for determining and controlling the condition of a spark ignition internal combustion engine involves detecting a physical value of combustion varying in association with combustion in the combustion chamber, then calculating the heat evolution rate from the physical value, and then determining the adjusting the combustion condition in dependence on the falling area of the heat evolution rate.

摘要： An ignition timing controller is furnished for use in a spark-ignition internal combustion engine. The controller includes a device for setting the ignition timing of the engine in accordance with the state of operation of the engine and another device for actuating an ignition system on the basis of the ignition timing set by the ignition timing setting device. The ignition timing setting device is constructed of a device for estimating the wall temperature of a combustion chamber of the engine from a variable, which indicates the quantity of combustion energy of the engine, and another device for calculating the ignition timing from the wall temperature of the combustion chamber estimated by the wall temperature estimating device.
